BACKGROUND:Since percutaneous injection of bone cement vertebroplasty has been successful y used in treatment of spine fracture, percutaneous vertebroplasty is trying to be utilized in the treatment of vertebral hemangiomas.
OBJECTIVE:To evaluate the safety and effectiveness of percutaneous injection of bone cement vertebroplasty in the treatment of symptomatic vertebral hemangiomas.
METHODS:Total y nine patients with symptomatic thoracic vertebral hemangioma patients, including two males and seven females, had back pain. Of them, two cases suffered from nerve root irritation. Percutaneous vertebroplasty with bone cement was used alone. Postoperative clinical and radiographic fol ow-up was conducted.
RESULTS AND CONCLUSION:The success rate was 100%, and no pulmonary embolism or nerve injury appeared. Postoperative imaging showed no leakage of spinal canal or foramen. At 24 hours after treatment, the symptoms had eased;nine cases were fol owed up for 3 to 36 months, showing that the original symptoms and signs disappeared or almost disappeared, no recurrence of vascular tumors. Results indicated that the percutaneous injection of bone cement vertebroplasty for the treatment of symptomatic vertebral hemangiomas is a safe and effective treatment;it can not only relieve symptoms, but also can increase the stability of the vertebral body, and prevent compression fracture and recurrence.

BACKGROUND:Bal oon kyphoplasty is a new technique of microtraumatic surgery of spine developed in recent years, and brings a new pathway for the treatment of osteoporotic vertebral fracture in the elderly.
OBJECTIVE:To investigate the therapeutic effect of percutaneous bal oon kyphoplasty on osteoporotic vertebral fracture, and to explore the main point of injecting bone cement.
METHODS:A total of 22 patients with osteoporotic vertebral fracture at the age of 60-78 years underwent percutaneous bal oon kyphoplasty under C-arm fluoroscopy. In accordance with the standards of WHO, antalgic effects were evaluated. The injection time, manner and dose of bone cement were analyzed.
RESULTS AND CONCLUSION:Al patients were fol owed up for 1-12 months. Postoperative pain was completely lessened in 15 patients, and partial y relieved in 7 cases, with an effective rate of 100%. Spinal mobility increased. No incision surgery was needed in al patients. No complications such as pulmonary embolism or nerve injury appeared. These results indicate that percutaneous bal oon kyphoplasty for treatment of osteoporotic vertebral fractures is minimal y invasive and simple, has less complication and effectively reconstructs vertebral body strength, and can better al eviate the pain, is an effective minimal y invasive spinal treatment technology. To strictly understand the main treatment point can obtain satisfactory clinical curative effects, including precise diagnosis of the disease, identification whether patient’s pain is induced by fractures, preoperative intraoperative exact localization of the affected vertebra, perfect puncturing technique, suitable postoperative treatment and nursing. It is also important to strictly master the time of injecting bone cement and the dose of bone cement. Bone cement injection was commonly done in drawing-wire stage. Too early injection easily induced leakage and toxic reaction. Too late injection affected the expansion of bone cement and therapeutic effects. The injection of bone cement should be finished under a perspective environment, which can effectively avoid bone cement leakage.

The therapeutic course lasted four monthes. Results: Nitroglycerin consumption in treated group was lower significantly than that in control group. The effective rate was 94.8% in the treated group and 84.2% in the control group after four monthes ( P

Objective The aim of this study was to investigate the relationship of gastric mucosal lesions and the parietal oxyntic function in rats under stress as a result of seawater-immersion after open abdominal injury. Methods Thirty-two SD rats were subjected to open abdominal injury followed by seawater immersion. The animals were randomly divided into four groups: control, 1h, 2h, 3h stress for 1h, 2h, and 3h groups. The pH value of gastric juice and gastric mucosal ulcer index (UI) were measured. The gastric mucosal lesions were observed with light microscopy, and the ultrastructural changes in parietal cells were observed by transmission electron microscopy. Results There was a significantly negative relationship between UI and pH value (r=-0.70,P

Objective To explore the clinical efficacy of Chinese traditional medicine combined with western medicine in the treatment of cirrhosis with ascites and hypoalbuminemia. Methods The trial group was treated with Chinese traditional medicine (modified decoction for Zhongman Fenxiao) combined with western medicine (drugs for protecting liver, diuretis, etc.). The control group was simply treated with Western medicine. Results After 4 weeks of treatment, the cure rate of the trial group was 43.75% and the total effective rate was 87.50%, significantly higher than that of the control group with 30.00% and 80.00%, respectively (P 0.05). The liver function in the control group was greatly decreased than that in the trial group (P

ObjectiveTo observe the curative effect of lumbar traction and Huantiao point-injection in the same side on lower limb pain induced by prolapse of lumbar intervertebral disc.Methods86 patients with lower limb pain induced by prolapse of lumbar intervertebral disc were randomly divided into the treatment group and control group with 43 cases in each group. Patients of the treatment group were treated by Huantiao point-injection in the same side and lumbar traction, and cases of the control group were treated by lumbar traction only.ResultsThe recovery rate of the treatment group was higher than that of the control group (P<0.01) after 3 weeks treatment.ConclusionThe effect of lumbar traction and Huantiao point-injection in the same side on lower limb pain induced by prolapse of lumbar intervertebral disc is better than lumbar traction only.

Objective To explore the difference of serum oxytocin levels between autistic children and healthy children at the age of 3-5,and the relationship between serum oxytocin levels and social competence in children with autism.Methods Twenty-five autistic children and twenty healthy children were tested by an enzyme-linked immunosorbent assay to evaluate the oxytocin levels;the SRS was used to evaluate social competence of children with autism.Results Mann-Whitney test showed there were significantly differences in oxytocin level between autistic children and healthy children(P<0.05).The social competence of autistic children was negatively correlated to oxytocin levels(r=-0.735,P<0.01).Multiple liner regression analyses showed that oxytocin level was an impact factor of the social competence of autistic children(F=11.931,P<0.01).Conclusion This study indicates that the serum oxytocin level maybe a factor which influence the social competence of autistic children.

Objective:To evaluate the immunogenicity of an experimental SARS-CoV inactivated vaccine.Methods:The virus suspension of F69 strain was inactivated with 0.4% formaldehyde and purified,then used as the immune antigen combined with Freund′s adjuvant.Eight adult New Zealand rabbits were immunized 4 times with this vaccine.12 sets of rabbit serum were sampled from the third day to 74th day after first immunization.Titers of specific IgG antibody and neutralizing antibody were determined by indirect ELISA and micro-cytopathic effect neutralizing test.Results:Rapid and potent humoral immune responses were induced by F69 inactivated vaccine in all eight immunized rabbits.Both specific IgG antibody and neutralizing antibody all peaked just with 2 vaccinations,with the maximum titer of 1∶81 920 and 1∶20 480 respectively about 6 weeks after first immunization.Across neutralizing reaction existed between F69 and Z2-Y3 strains.Conclusion:F69 inactivated vaccine owns strong immunogenicity.Similar antigenic epitopes exist between the F69 strain and Z2-Y3 strain,which ensured the cross neutralizing reaction.

Objective To explore the value of an advanced reciprocating gait orthosis (ARGO) combined with comprehensive rehabilitation treatment in rehabliltating complete spinal cord injury (SCI) patients. Methods Twelve patients with complete SCI at the T4~L2 level were fitted with an ARGO. Before and after fitting the ARGO,comprehensive rehabilitative excecises were conducted. After training, ambulation was evaluated, and competence in the activities of daily living was evaluated using the Barthel index and Functional Independence Measure. Results The patients' ambulation improved markedly after fitting the ARGO and training. Barthel index and FIM scres improved significantly. All 12 patients achieved therapeutic or functional ambulation. Conclusion With the aid of an ARGO, patients suffering from complete SCI below the T4 level can achieve functional walking and improve their quality of life.

Objective To investigate the optimal workflow and protocol for integrated PET/MR by comparison with PET/CT.Methods A total of 228 patients were enrolled in this study for PET/CT and PET/MR evaluation on the same day.Six PET/MR protocols with different MR sequences but the same PET acquisition protocol were investigated and the optimal protocol was identified based on image quality,acquisition time and diagnostic performance.Results PET/MR workflow was similar to PET/CT,however,some special issues needed to be considered for PET/MR.Among the 6 protocols,protocol No.6 outperformed others for body and head regions.Types of artifacts were found more often in PET/MR than in PET/CT.Conclusions By optimizing the protocol,PET/MR could achieve almost the same diagnostic performance as PET/CT.However,the issues of long acquisition time and artifacts on PET/MR need to be further improved.
